First Pass Yield (FPY)
Definition: The difference in units produced (output) by a manufacturing process over a certain period of time compared to the units that went into production (input) over the same period of time – i.e., output vs. input.
Discussion: The First Pass Yield (FPY) key performance indicator measures the calculation of the units produced from a manufacturing process compared to the units that went into production -- essentially, input vs. output. For this value you typically want it to be as high as possible. A below average number for this KPI could be an indication of an inefficient manufacturing process, resulting in surplus materials or products with high production costs.
